python - 使用python编写文本文件

Question

如何使用 python 将下面的测试准确地写入文本文件？当我必须编写多个具有不同参数的文本文件时，这是必需的。

MY_FILE = E:\test.jpg

BAND_SUBSET = ( 1 0 0 )

SPATIAL_SUBSET1 = ( 25.0 50.0 )
SPATIAL_SUBSET2 = ( 25.0 50.0 )

PARA1 = (
 0.0 0.0 0.0
 0.0 0.0 0.0 )

END = END

Answer 1

with open('somefile.txt', 'w') as fp:
  fp.write('''MY_FILE = E:\test.jpg

BAND_SUBSET = ( 1 0 0 )

SPATIAL_SUBSET1 = ( 25.0 50.0 )
SPATIAL_SUBSET2 = ( 25.0 50.0 )

PARA1 = (
 0.0 0.0 0.0
 0.0 0.0 0.0 )

END = END''')

Answer 2

with open('fileName', 'w') as f:
    f.write(yourString)

在哪里

>>> yourString = """MY_FILE = E:\test.jpg

BAND_SUBSET = ( 1 0 0 )

SPATIAL_SUBSET1 = ( 25.0 50.0 )
SPATIAL_SUBSET2 = ( 25.0 50.0 )

PARA1 = (
 0.0 0.0 0.0
 0.0 0.0 0.0 )

END = END"""

您可以使用以下代码替换这些值。

with open('fileName', 'w') as f:
    f.write(yourString.format(band_subset, spatial_subset_1, spatial_subset_2, para1))

在哪里

yourString = """MY_FILE = E:\test.jpg

BAND_SUBSET = {}

SPATIAL_SUBSET1 = {}
SPATIAL_SUBSET2 = {}

PARA1 = {}

END = END"""

始终使用该help函数或查阅 Python 文档。

write(...)
    write(str) -> None.  Write string str to file.
